- Abstract:
-
In the hilling area of Keshiketeng County,the natural environment has deteriorated due to long-term tilling and crop production.In order to recover and rebuild the ecosystem large scale ecosystem construction projects have been implemented under the leadership and instruction of the local governmennt.Summarizing the achievement in comprehensively treatment to the deteriorated ecosystem and the improvement to the environment in a small basin,the authors made an analysis on the economical situation.The conclusion of the paper could be a scientific reference for future basin treatment practices.Based on the example of Dadonggou small basin in Keshiketeng County and adopted the Cobb-Douglas Equation,the author took the irrigated land area per person,the coverage of trees and grasses and the treatment ratio to the soil and water erosion as the three affecting factors,made an analysis on the productive elasticity and the value of marginal change.It has been concluded that the elasticity coefficient of the three affecting factors are all positive and among of them the irrigated land area affected the most.This shows that the three affecting factors are all very important for agrocultural production,the irrigated land area is the first importance.After the erosion in the Dadonggou small basin has been controlled,the vegetation,crop production and people’s income are all have been increased.
